What is an off-grid power supply?
The power grid ensures the continuous presence of electricity. One need only turn the light switch and the electrical infrastructure provides the transmission of power to turn on the lamp. In other words, the power grid ensures the continuous presence of power to meet the varying power needs of the customer. This, of course, up to the contracted power that the customer has agreed to with the grid operator.
Unfortunately, increasing grid congestion is making the grid less and less reliable. For companies that depend on the grid, this is a big problem. But what if you can become independent of the grid? We would like to explain to you how you can be self-sufficient in power with an off-grid power supply.
Off-grid: self-sufficient in electricity
An off-grid power supply is an energy system that operates independently of the power grid. The electricity is self-generated and used without using the grid. An off-grid power supply always consists of a combination of power generation installations, an energy storage system, and smart control technology to convert varying energy production into continuously available power suitable for electrical equipment. With these installations
Complete infrastructure
In remote areas such as islands or natural areas, off-grid power replaces the electricity grid. This requires a permanent infrastructure for energy generation, storage and management. Through solar panels, wind turbines or smaller hydroelectric systems when there is sufficient running water, renewable energy is converted into electricity. This is stored in a battery system.
Appropriate control systems, such as an inverter and an energy management system, ensure that generation, storage and consumption are properly balanced. The inverter serves to convert direct current from renewable energy sources into alternating current for electrical appliances.
Main components of an off-grid power supply
Inverters
These convert electricity from the batteries (direct current) into the kind of electricity your devices need (alternating current), such as a charger for your phone that makes power suitable for your phone.
Energy storage system
This stores the electricity your energy sources make, so you still have power at times without generation.
Controllers and monitoring systems
- Charge regulators: These keep the batteries from being overcharged or completely drained.
- Energy management systems: These keep track of how much electricity you use and how much you generate so that everything runs smoothly.
Energy sources
- Solar panels: These convert sunlight into electricity. They work well on sunny days and are ideal for locations with lots of sun.
- Wind turbines: These use wind to make electricity. A good source of energy in places with lots of wind.
- Hydropower: Power generated by turbines in flowing water. This is widely used in countries with many mountains and water, such as Norway.
- Generators: These use diesel or gasoline to make electricity. This can be a backup option for when solar or wind is not available. This energy source creates the mostCO2 emissions and is therefore not preferred.
Off-Grid Power Supply: the benefits
Independence: You are not dependent on the power grid and can be self-sufficient. You therefore do not suffer from grid congestion.
Reliability: In areas where the public grid often fails, your own system ensures reliability. So you can be sure you’ll always have power.
Environmentally friendly: Especially if you use renewable resources such as solar and wind, you help the environment by reducing CO2-emissions.
The right Cellpower ESS for off-grid power supplies
We advise and think along with you to achieve a sustainable off-grid power supply. With five Cellpower ESS models – from a compact 102 kWh entry model to a liquid-cooled total system of 3,440 kWh – there is sufficient storage capacity for every situation. We look for a complete solution, including a suitable energy management system as well as installation and maintenance of the systems we supply.
